You may have heard of this lately, or perhaps have had it happen to you. That's right...your internet browser gets hijacked. Taken from your control, as it were.

It takes you to sites you would never have visited in a million years; your computer slows down and maybe crashes; your homepage is mysteriously changed; you now have about a dozen "favorites" that you never selected and don't want.

You've been HIJACKED!

What happened? How? You ask, as you pull your hair out in disgust.

Well, it happened to me,, and some FReepers I know, and a LOT of my friends, lately. I've been hearing scuttlebutt around the Web, and around the water cooler. People's computers are being taken over by insidious, rotten spyware and malware that effectively seizes control and can have serious reperussions for the user.

These things download some particularly nasty porn, even child porn, to a computer. People have been fired, investigated, and disgraced for something they never did.

I discovered mine one day whil, of all things, trying to access FR. I mistyped the URL, and found myself redirected to some porn search engine. Massive popups overwhelmed my Pop-up Stopper, and froze my computer.

After the reboot, I ran my McAffie antivirus, which quickly crashed the system and failed to ever work again. Ad-Aware removed some registry keys and values, and I thought all was well.

Wrong. It happened again.

Now, I got serious. I obtained Symantec Pro version, and ran it. It caught several more bugs, but some couldn't be quarantined OR removed.

I was in a fix. I was using a computer that FReeper thumperusn had graciously loaned me, and I didn't want to give it back to him all jacked up. Thus began my battle with the Internet demon known as "CoolWebSearch".

With over 25 versions to date, and about 30 affiliated sites, CWS has infected millions of computers to date. It uses a "hole" in JavaScript Virtual Machine to invade your machine and make changes to IE and your registry. It also copies itself to your "restore" files, which the antivirus and anti-spyware programs DO NOT search or modify.

After educating myself, and wading through literally hundreds of pages of "geek-speak", I formed a plan of attack.

PROTECTION

First, I would fix the holes in my system. The borrowed laptop used Windows Me, from 2000. It needed updating, and MS's website had a whole bunch of them. Since I'm on a dialup, it took hours to download and install all the patches.

Next, some firewalls. At Major Geeks.com, I found and downloaded Zone Alarm and Browser Hijack Blaster, both for free. Thus protected from further invasion, I set about curing the disease.

MEDICINE FOR A SICK COMPUTER

I first updated the Symantec to the latest standards. I then did the same with Ad-Aware, and downloaded Spybot Search&Destroy from Majorgeeks. It was about then I discovered that I was not alone.

I found Merjin.org, a website set up by a computer student with the sole purpose of combatting CWS. From there, I obtained the invaluable CWShredder, a program that can remove ANY CWS bugs, and which is updated frequently. I also got HiJackTHIS!, a program which can find and display anything that is downloaded to your computer, and remove it with a command.

So effective are these programs, CWS has recently conducted Denial Of Service attacks on Merjin.org. Thankfully, it has survived...it also contains detailed information about all the CWS variants, and manual removal procedures.

I was able to sweep my system clean of many more bugs. Unfortunately, I still wasn't done.

HEALING THE PATIENT

I was still getting some spyware from CWS, and some Browser Helper Objects (BHO's) were still turning up. Fortunately, due to Zone Alarm and Hijack Blaster, I was warned well in advance. However, I was suspicious as to how it was happening on a daily basis. Thus, I went even deeper.

I went to Symantec's website and downloaded detailed instructions for THOUROUGHLY cleaning your system. I had missed something important.

CWS also writes itself to your "restore" files. These are immune from the cleaning software. The cure for that was quite new for me, a relative computer novice. However, one learns by doing, so I plowed ahead.

I disabled the "restore" function (instructions from Symantec), and rebooted into "safe" mode(also on Symantec's instructions). I then ran all my cleaning and anti-virus/anti-spyware programs, deleting everything found.

Then, I went to the C://System/Restore files and deleted them all. If it affects the "restore" function adversly, I have not seen evidence of it yet.

I rebooted, performed a scandisk and a defrag, and rebooted again. Then I enabled the "restore" function once more.

That was yesterday, and so far, so good. I'd like to think I got it all, but with these bugs, you never know. Fortunately, I'm now forewarned and forearmed.

I wanted to put this out because I'm SURE that there are numerous FReepers who might have had the same problems. Make no mistake...these bugs can be ruinous to one's job and reputation, and they are out there on many innocent sites. A simple popup is all it takes to get one.

I read many articles on people whose lives were nearly wrecked by them, and who were so repulsed by what they got that they threw their computers away, and swore to never use the 'net again.

There is no legal recourse; CWS and others like it are buried under many layers of internet cover. The company itself denies any wrongdoing.

Please, if you've got similar experiences, share them. Others might benefit from this knowlege, and if you've got links and advice, please share it here, too.

As an alternative to a lot of the stuff you mentioned, one solution that solves many if not most of the problems, would be to simply stop using IE. Download Mozilla and install it. You will be protected from popups, and a lot of the nastiness you encounter with IE. Aditionally, once you use tabbed browsing, you'll wonder how you lived without it.

(The Great Experiment is over.)

I run Ad-Aware daily after an Internet session, and also CWShredder and HijackTHIS!. I update all my antivirus/anti-spyware weekly, and keep my system updated as well. I also, just before shutdown, delete ALL cookies and history files, followed by the emptying of the recycle bin.

It takes a little time, but peace of mind is worth it. These bugs pretty much compromise your whole system...even sending personall information back to their masters in some variants.

(Certainty of Death, small chance of Success...What are we waiting for?...Gimli the Dwarf)

Oh, that's an ugly one, all right. May I suggest cloning your system with Symantec's Ghost as one means of keeping a backup copy offline? The malware can't get to it if it's sitting in an envelope on your desk...

I now am cleaning spyware/adware/trojans from computers several times a week.

Most of these machines have become unusable because of it.

The latest genuine threat is Peper. This nasty piece can't be killed until you go into safe mode, delete a pile of hidden files and clean out the registry of BHOs.

I will say this...unless you run a popup stopper and/or an ad remover, you're going to get this garbage.

You need to get and run:

Spywareblaster spybot search and destroy Adaware hijackthis

Further stop using Internet Explorer. Switch over to Mozilla Firefox. At least until this garbage is kept at bay.

Firefox is also VERY extensable. Imagezoomer is a great add-in to firefox. Allows you to zoom in or out any image in any post. There are over 100 add-ins to Firefox that add all sort of nifty things. Firefox displays pages just as fast or faster than IE(if someone tells you otherwise, they have an OS problem, I've installed it on over 50 machines) and Firefox blocks popups and much of the adware issues we've got right now.

Man is this a timely thread. I just spent a couple hours getting rid of this crap on my computer. But here's something I can't solve. For some reason my "Favorites" will only except 4 addresses. If I try to add more, it shows up until I close my browser, and then doesn't reappear. Any ideas?

It has gotten to the point that I rarely venture off of FR. I find myself waiting for commentary on an article rather than clicking on the source for the full story. I use spybot and adaware. The web can be a realy dangerous place.

This is interesting... I haven't had known crashing kind of problems you have had, no ~known~ infection, but I always have several entries in my DNS cache (which I understand to be contacts from my computer to the internet) that are ~not~ places I have been to and have very insidious names. I can flush my DNS cache, but all these re-appear immediately without ~me~ doing anything. Note below that I flushed the cache and then immediately displayed again. I did nothing else, and refreshed no pages in between.
